In this paper, a diffusion–reaction continuum damage model is proposed to study the oxidation behavior of high-Cr steels in supercritical water. The model is formulated based on a three-dimensional (3-D) setting. By considering the diffusion and reaction effects of free oxygen in a domain of solid m...
